The house wren is a very small brownish songbird and a member of the wren family of Troglodytidae. Despite its lack of bright colors, you've probably seen them before bouncing about with their active, inquisitive nature. Its short tail is usually pointed up in the air, pausing regularly to sing a cute snappy song. Wrens are a small attraction that add enthusiasm to backyards across America. Various forms of wren are found all over the American Continent.
"The House Wren was named long ago for its tendency to nest around human homes or in birdhouses."
Both the male and female wren exhibit their singing and calling abilities. The sounds they make will vary according to their needs and reactive behavior. Males have a unique sound pattern during mating season and females sing mainly in answer to their mates shortly after pairing up. Their singing can include high-pitched squeals that are not like any wren sounds that the male wren will make. Wrens don't usually sing after mating season, however, wrens will make a variety of harsh sounds, often in response to preators and other animals that pose a threat.
Even though Wrens are not picky about their choice of dwelling places, there are a few things you should consider, and that is the type of wood and size dimensions. When choosing a wren house to hang in your yard, choose one that is constructed with cedar, since cedar breathes well, is lightweight and resists insects. The size dimensions of the entrance should be no bigger that about 1 1/8" in diameter. If the entrance is larger, then the structure should not have a perch so that it will not attract undesirable birds and predators, and wrens don't prefer perches, as landing ledges or slots work better.
Wren houses are sometimes built as a side-mounted birdhouse, and come in sizes and shapes that vary slightly from one to another. However,hanging wren houses usually feature a traditional shape which makes them stand out more as a recognizable birdhouse style. You've probably noticed them before hanging in someone's front porch or backyard. It's usually a plain square or diamond shape structure with an overall conservative shape. The front face is sometimes painted with cutsie bird graphics with bright background colors. The roof is a right-angle shape with a roof ridge that points up, and eye-hooks that enable it to hang from a rope or chain as the preferred way of mounting.
It's difficult to get any bird species to choose a hanging structure to live in. The reason for this is because birds have an incredible ability to sense the safety and effectiveness of a structure. Their instincs tell them what works and what doesn't. However, there are a few species that have no problem with a birdhouse structure that hangs, and one species of bird in particular is a House Wren. In fact, these types of birds will sometimes nest in very unassuming places, for example, empty bottles, old radiators, milk cartons, etc.
